Dimwitty Duck is a supporting character of Donald Duck introduced in February, 1968. The two are possibly distant relatives. He is not very bright and seems to be a version of Goofy as a duck. He was introduced as a sidekick to Donald, mirroring the relationship of Goofy to Mickey Mouse. He was eventually developed into the sidekick of Moby Duck, another presumed distant relative. Their relationship still mirrors the Goofy-Mickey one, the bright dominant character and his naive and error-prone sidekick.His signature phrases are "Gawrsh", "Duh-h" and "Aye-aye".
